BACKGROUND Drug therapy is mostly employed in the management of supraventricular tachycardias (SVTs). However, radiofrequency catheter ablation has been found to be highly effective and safe in the treatment of SVTs. The current study is aimed at sharing our experience of 320 patients who presented with SVTs, and were treated with radiofrequency catheter ablation. METHODS This descriptive stu...

Radiofrequency ablation is typically used to heat up malignant liver tissue to critical temperatures in order to kill cancerous cells. However, this hyperthermic process also has noticeable effects on the microvasculature of tumor tissue (i.e. capillary blood vessels). Specifically, it has been empirically shown that heating up cancerous tissue also affects blood flow and oxygen transport. Math...

Clinical evolution of the colorectal carcinoma occurs in up to 60% with colorectal liver metastases (CRLM). Although hepatic resection is considered to be the golden standard in CRLM, novel less invasive techniques have emerged, of which radiofrequency ablation has received a high credibility. When tumors are not eligible for surgery, guided radiofrequency ablation is considered an alternative....

BACKGROUND Cardiac MRI offers 3D real-time imaging with unsurpassed soft tissue contrast without x-ray exposure. To minimize safety concerns and imaging artifacts in MR-guided interventional electrophysiology (EP), we aimed at developing a setup including catheters for ablation therapy based on carbon technology. METHODS AND RESULTS The setup, including a steerable carbon catheter, was tested...

Radiofrequency ablation for rhythm disorders is limited by the inability instantaneously to visualize and monitor ablation lesions and by the mismatch between immediate injury and irreversible conduction block. Magnetic resonance imaging (MRI) thermometry only approximates the extent of irreversible lesions. Late-gadolinium enhancement (LGE) MRI correlates with histological lesion volume but ca...

Patients with late-stage cancer commonly have distant lymph node metastasis; however, poor health often contraindicates surgical treatment. Although the quality of life and overall survival for these patients are low, there is neither a consensus nor a guide for treatment. Ablation technique and surrounding tissue damage are two possible reasons for limited study of radiofrequency ablation in p...

conclusions the accompanying case series suggests that this protocol is deserving of randomized, prospective study. results c-rfa of the genicular nerves after using the described selection protocol resulted in > 90% pain reduction, improved function and avoidance of surgery at 6 months in all four cases. all opioid and analgesic medication use decreased or was unchanged in all cases. no seriou...

Intramural septal substrate presents a challenge in patients undergoing ventricular tachycardia ablation, terms of both accurate mapping and ablation with unipolar radiofrequency energy. We present the first use novel 2-F octapolar catheter accurately defining intramural scar facilitating bipolar ablation. (Level Difficulty: Advanced.)

The cost of definitive therapy was compared in 25 patients who underwent radiofrequency catheter ablation of accessory pathways in 1990 and 25 patients who underwent surgical ablation of accessory pathways in 1989. In the radiofrequency group, 23 of 25 patients had a single accessory pathway and the remaining 2 patients each had 2 accessory pathways. In the surgical group, 20 patients had a sin...
